Photoed by me late last month (just before I attended this (already mentioned here in passing (she is a friend (and it went brilliantly)))):

Yet more evidence of how digital photography has encouraged temporary art, by making it digitally preservable. What we see is videoing, I think. But we can be sure that a straight up still photo of the final result will be included in the photography process.

Note the silver paint, on top of what was there before. If the previous occupant of this spot (in the Leake Street Graffiti Tunnel) didn’t have what he had done photoed, he has only himself to blame.
